The greenhouse gases threat to world ecosystems is a very real threat. These gases help contribute to global warming and air pollution. Because of the increase in the level of these gases in the atmosphere, severe weather patterns are becoming more common as the ocean slowly warms up. Devastating storms and hurricanes are occurring more frequently, and new viruses and bacteria that pose a threat to humans are being found, all because the temperature of the earth is warming faster due to greenhouse gases. The world ecosystems are changing and being threatened because changing climates and global warming. Stopping the emissions of greenhouse gases can stop this threat, and preserve the ecosystems of the world.
Loss of tropical rainforest biome may be a catastrophe for mankind as well. The rainforest creates the oxygen that you breathe and holds the answers to many natural cures and medical treatments that are not yet all revealed. This crucial resource is being deforested at a rate of tens of millions of acres each year, and this is an enormous loss. Scientists estimate that many species of unknown plants, insects, and animals are destroyed without ever being discovered or studied, because of deforestation in the rainforest. This natural resource is an important part of the entire global ecosystem, and life on earth depends on it. The rainforest loss that goes on every day damages the earth, and the entire population. Steps need to be taken to protect and preserve this vital resource, which also acts as a filter and removes very large amounts of carbon and pollution from the air.
Another issue that affects the global ecology involves ecological concerns about us offshore oil drilling. No matter how safely offshore drilling is done, this process harms the environment and the ecology. Oil exploration methods can harm marine life, and oils spills and accidents during transportation happen many times each year. Drilling, whether it is offshore or on land, destroys the area and has high risks of environmental damage and dangerous contaminants. One oil spill in the ocean can spread quickly and affect many miles of marine life and environment. When large transportation spills happen, like the one involving the Exxon Valdez ship, the environment and area populations can suffer for decades, even with massive cleanup efforts.
Traditional mining and drilling deplete natural resources as well as harming the environment. Mountains are destroyed simply to gain easier access to fossil fuel deposits like coal seams, and fossil fuels are limited and can not be renewed. These fuels take thousands and even millions of years to be created in the earth, and once these reserves are gone they can not be replaced. Alternative energy sources that are renewable and eco-friendly must be utilized to prevent an energy crisis globally. The technology has been developed for a number of alternative energy and fuel sources which do not harm the earth or environment, and are renewable. These alternative energy sources can be produced domestically, and will end the dependence on fossil fuels and foreign oil. Using fossil fuels, and traditional recovery methods like mining and drilling, will not supply the energy needed globally for much longer, and have an enormous detrimental effect on the environment.
