Global warming has been believed to be beneficial for the food and agricultural industry for quite some time. This is due to the high levels of carbon dioxide from global warming which were once thought to help with photosynthesis for the greeneries, thus, the belief that there will be a boom on the agricultural sector and food supply.
The theory was backed by the fact that there has been a great improvement in barley production in Iceland amidst global warming. But as more research experiments have been conducted, it was revealed that global warming effects on food supply and agriculture are not good at all.
Photosynthesis is necessary for plants to grow and manufacture their own food, but with the drastic increase in temperatures brought about by global warming, these plants will find it hard to survive. In addition, the climate change has brought about weather irregularities, bringing in floods and hurricane – surely, the survival of t will be a total struggle. Furthermore, these plants are primarily used for human consumption and when they are affected by the prevailing high temperatures, food shortage will occur.
How Global Warming Affects Food Supply
It has now been established that global warming can have negative effects on agriculture and ultimately food production. These effects are:
Reduced yield - With global warming, expect that there will be reduced yields of food. High temperatures and drought can bring stress to crops and livestock, making them vulnerable to diseases and affecting their productivity.
Decreased soil arability – with the climate change, higher latitudes will receive the right temperature suitable for growing, only that the soil and nutrients found in these areas are not suitable for growing produce. Alternatively, lower latitude areas are suitable for farming but with the climate change, it becomes a less productive ground.
Need for Irrigation – In some parts of the world, crop production will depend on rain. However, since the rise in temperature makes rain absent most of the time; the need for irrigation becomes the next option. As a result, there will be more expenses to take care of and water access will also become a problem.
More Pests – Pests, fungi, and weeds tend to thrive better in warmer temperatures and under high levels of CO2. New pests may be introduced in different regions as environmental temperature and humidity changes. For instance, pests thriving in low-latitude areas may migrate to higher latitudes.
Effects on Fisheries – fisheries are already affected by pollution, global warming, and overexploitation. The changes in water temperatures in oceans, lakes, and rivers, coupled with rise of sea level and melting ice can have a great impact on different species of fish. For instance, they become more vulnerable to diseases in warmer waters. For some species of fish, they are fortunate enough to have adapted to the change by migrating to high latitude, but for others, like freshwater species, there is no other option.
Food shortage is a serious threat to society since man relies mainly on food for survival. The future of the global food supply will depend on how different societies can handle to the changes brought about by global warming.

The Issues We Face on Waste Today
Solid waste is considered garbage produced in our homes, offices, and industrial companies. The production of solid waste and its toxicity is increasing. Most of the products we buy from the market contain harmful chemicals, and when these products are combined with other chemical products, your health and our environment are at risk. There are different waste facilities for every nation including incinerators and landfills.
Humans Contribute Too Much Waste
The human race is responsible for more than 30% of the world’s generated waste. Just imagine how much household garbage you throw out every day. You tend to throw out trash of different kinds each day. It is in the form of paper (white paper, magazines, tissues), plastic (food container, bag of chips, medicine bottles), glass (food jars, beer bottles), food (vegetable peels, leftovers), and so much more - it is for certain that you can still think of a lot more examples.
In addition to the solid waste coming from your home, there are also pieces of trash lying out on the streets; those that come from the commercial sector such as restaurants, hospitals, and shops; the industrial companies, manufacturers, and the agricultural sector.
In the United States, about 220 billion tons of garbage per year is being produced as reported by the Environmental Protection Agency. While statistics for the entire planet are not readily available, just consider that the U.S. comprises 4% of the world population – that will simply tell you that it is a LOT.
The Toxic Nature of Waste
Government regulations on the chemical industry are not that stringent, which results to the manufacture of products that may contain harmful, untested chemicals. These products are consumed and eventually thrown away. There are still chemicals known to be harmful (such as BPA in plastic toys) that are still used due to poor regulation. The toxic nature of waste intensifies the problem and people do not really have a clear solution for the problem.
Packaging is definitely a serious contributor of solid waste and that a huge percentage of waste products come from packaging, which is made of plastic. Plastic does not biodegrade and it does not disappear even for centuries – and that will seriously wreak havoc in our environment. Imagine the lifespan of a plastic material and the fact that a lot of trashes thrown away are made of plastic – it is definitely concerning.
How Garbage Pollution Affects the Environment
Garbage pollution affects the environment in many ways. For one, the chemicals that are present in the waste are harmful to the environment and all living species. Garbage pollution is also a source of bacterial diseases. Uncontrolled trash problem can also radiate into something more serious like having the garbage find their way into rivers and streams, polluting the waterways and harming aquatic life.
The long-term effects brought about by trash problem are not easily reversible especially when chemicals are involved. While there are several campaigns and projects that aim to solve trash problems, it still helps if you make small contributions to prevent the problem from becoming worse.

The Issues We Face With Natural Resources Today
Life on Earth depends on the availability of the world’s natural resources, which includes water, energy, materials, and fertile land. However, the human population is growing at an overwhelmingly rapid rate, also increasing the rate at which these resources are consumed.
The climate is changing; freshwater reserves and our forests are diminishing; there are only a few land areas that remain fertile and different animal and plant species are threatened to extinction. If we want life to continue on this planet, we need to change our lifestyles and do what we can to preserve our natural resources.
The Issues with Natural Resources Depletion
Everything found in nature that can be turned into a product for consumption is a natural resource. The modern technology can do so much in the name of convenience but it is incapable of making trees. However, technology can modify these resources and as it is trying to take over the world, the rate at which these resources are depleted has increased dramatically.
It is important to understand that not all the resources found in nature are unlimited. But somehow, its depletion is inevitable due to the lifestyle we lead. Increasing demands due to population explosion, human greed, and neglect all lead to the loss of these precious gifts of nature.
Below are some of the common problems concerning our natural resources:
The quality of land worldwide is not as pure as it was a hundred years ago. Forests have been cleared out and have been replaced with agricultural lands and residential lots. Vast agricultural lands deplete more nutrients in oil much faster than the rate at which they are replaced. Fertile lands are decreasing, while consumption and demand continue to rise.
Our waters today are polluted as a result of waste products coming from industrial sites. Water pollution brings on several negative consequences. One is forcing the closure of beaches due to poor quality of water. Another is that fish may become unsafe for consumption. The potable water in your area could be contaminated with harmful microorganisms that can cause serious health problems.
The ocean is also at stake especially with the growing problems of global warming. The ability of the ocean to replenish fish population cannot keep up with the rate of consumption. On top of that, the climate change has also affected productivity of marine life.
The lush forests are threatened with continued deforestation to satisfy the economic needs of many nations. Biodiversity is greatly affected as the consequences are suffered by species that thrive in the forest, which could eventually lead to their extinction.
One Planet to Save
The human population takes up 30% of the Earth’s resources and our planet may not seem to keep up with the high demand. This leads to deforestation, polluted air and water, degraded soils, and the dramatic decrease of different plant and animal species. The problem intensifies as the human population and rate of consumption continue to increase and. If nothing changes, it is likely that this only one planet we have may not be able to sustain life.

The Issues We Face With Global Warming
The climate is changing; in fact, it has been changing over the last few decades. The earth is getting warmer and several scientific reports can prove this. What is sad about it is that the problem is mostly caused by humans. Global warming is a lingering problem and different animal and plant species and habitats tend to suffer more from this phenomenon. The result could be devastating – the balance in the ecosystem can be disrupted.
Global warming is a hot topic of the current environmental issues we face today. Its effects on agriculture, animals are already frightening enough. How much more when it comes to the human population? As most of the causes come from us, it is unfortunate to say that the effects it will have on us will be severe.
Causes of Global Warming
Global warming is caused by different factors but is mostly human-induced. In a small scale, we contribute harm to the environment through our actions, but when put together the millions of people in this planet, the impact can reach a global scale.
Carbon Dioxide Emissions
We depend on electricity so much that what we do not often realize is that this electricity comes from power plants that burn coals. As this process takes place, carbon dioxide –in great amounts – is released into the atmosphere. You can just see how trendy electronic gadgets are today, which only means that there will be an increase demand for electrical supply.
The demand for cars is also increasing due to the alarming growth of population. More and more people need cars for transportation and as a result, there is an increased use of fossil fuels. It goes back to carbon dioxide emission as we burn gasoline for transportation.
Deforestation
Our forests are rich in resources and wood is one essential resource greatly needed in any part of the world. We need wood for different purposes – paper products, furniture, construction, and the like – and as the demand increases due to population growth, deforestation results. Forests are there to help remove and store excess carbon dioxide in the atmosphere. But increasing deforestation onlycontributes to the accumulation of carbon dioxide, further harming the atmosphere.
Carbon dioxide emissions and deforestation are not only the causes of global warming. There are plenty more and if we do not do anything about it, pretty soon the Earth will be a difficult place to live in.
The Devastating Effects of Global Warming
Climate change is the most obvious effect of global warming and has been around for the past decade. Frequent storms, irregularities in weather, rising sea levels, and melting glaciers are just some of the obvious signs of climate change.
Our natural resources will soon deplete due to our greed. Human activities such as agriculture, fishing and mining can result to the degradation of these resources. If this trend does not stop, it is only a matter of time that we will exhaust our natural resources.
The List Does Not Stop
The environmental issues brought about by global warming are not just limited to what has been mentioned above. There are more issues that surface each day making the list of problems longer as time passes. If we do not take action, even the simplest ones, we may not have any other option but to suffer the consequences.
