Multinational corporations like Monsanto claim that GM crops require fewer applications of herbicide compared to non-GM crops, which reduces the harm to the environment. However, in South America the standard before adoption of GM crops was agricultural traditions that often times did not include any chemicals intensive means to treat weeds. This means that even though GM crops might take less herbicide compared to typical standards in North America, GM crops are ultimately causing more herbicide to be used in South America. There is also a concern that “as chemical control of weeds becomes the norm in developing country agriculture, the potential exists for the emergence of herbicide resistance species that do not respond to the increased chemical treatments.” This only promotes the use of more herbicide which increases the harm to the environment. There are also problems because GM crops have toxins in them.
Could you imagine a world without rainforests? Well, it may very well become our future. Unfortunately, there are multitudes of problems that come before and after deforestation in the Brazilian rainforests. There is only a finite amount of natural resources we can use on a day-by-day basis and lumber from the Brazilian rainforests is decreasing rapidly. The animals that thrive and procreate in the rainforests will be left with no shelter and could increase their chances of becoming extinct.
Farmers began to clear trees for land. Other people flooded the forest looking to obtain the wood or build there house in the forest for a cheaper price. The final and main cause of deforestation is the need for flat, treeless land. Most trees are cut down in order to create room for housing. The flat land is used for urbanization as well as cattle ranching.
What is global warming? Global warming is defined as “ an increase in the earth 's average atmospheric temperature that causes corresponding changes in climate, and that may result from the greenhouse effect" (“Global warming”). Natural events and human that causes global warming are believed to be factors to increase in average temperatures. This essay looks into the growing problem of global warming and suggests reasonable solutions to it. It also evaluates the effectiveness of these solutions.
Climate change otherwise known as global warming has been an ongoing issue for decades. Beginning in the 19th century, climate change has increasingly affected Earth and its atmosphere. Rising levels of carbon dioxide are warming the Earth’s atmosphere causing rising sea-levels, melting snow and ice, extreme fires and droughts, and intense rainfall and floods. Climate change has and will continue to affect food production, availability of water, and can add to many health risks in humans and animals. In fact, in an article by Justin Gillis titled, “Scientists Warn of Perilous Climate Shift Within Decades, Not Centuries” he focuses on a paper written by former NASA climate scientist, James E. Hansen, explaining the effects of climate change
This is changing the natural systems that take place in our atmosphere. When all these extra gases are released, carbon dioxide stars to accumulate in the atmosphere. Climate change is a global issue because when the temperature of the Earth changes even very slightly, it can cause droughts and our crops can die. This is affecting our food supply. Also, when water levels rise even slightly, it can be very destructive for
There can also be affects on the types of storms that can occur if global warming continues. Scientists say that category three storms can turn into a more dangerous category fours. Farms and cities will face new pests, heatwaves, heavy downpours, and increased flooding. There can also be many causes in disruption of habitats and this can lead to many animal species to extinction. Global warming is a rise in the surface temperature of the earth.
The atmosphere becomes more dry and the climate starts to get warmer. With less trees, areas can now dry out and become barren. This could drastically change the species lives living in those areas. Species that live in places where deforestation occurs are victims of the negative effects it has on the environment (TS). According to The World Counts, “70% of our world’s plant and animal species live in forests,” and when deforestation happens, animals lose their habitats.
It occurs due to rise in global warming which occurs due to increase in temperature of atmosphere by burning of fossils fuels and release of harmful gases by industries. Climate change has various harmful effects but not limited to melting of polar ice, changes in seasons, occurrence of new diseases, frequent occurrence of floods and change in overall weather scenario. • Loss of Biodiversity: Human activity is leading to the extinction of species and habitants and loss of bio-diversity. Eco systems, which took millions of years to perfect, are in danger when any species population is decimating. Balance of natural processes like pollution is crucial to the survival population is decimating.
