very short speech of 2 min on global warming
Answers
One of the biggest problems facing the world today is global warming. Many scientists believe that our production of carbon dioxide and other greenhouse gases is having a heating effect on the atmosphere, and this could be very dangerous for human life.
This essay will examine the problem of global warming and suggest some ways of solving the problem. Many problems could result from global warming. One of the biggest problems is rising sea level. This could result in the flooding of low lying coastal areas and cities, such as Egypt, the Netherlands, and Bangladesh. Some countries might even disappear completely!
Another problem caused by global warming is changes in weather patterns. Many areas of the world are experiencing increased hurricanes, floods, and other unusual weather. A third problem associated with global warming is the effect on animals. Fish populations could be affected, while some insects which spread disease might become more common. There are several things we can do to solve the problem of global warming. One solution is to stop producing C02. We can do this by switching from oil, coal and gas to renewable energy. Another solution is to plant more trees.
Trees absorb carbon dioxide and produce oxygen, which is not a greenhouse gas. A third solution is to use less energy and to recycle more products. Generating electricity is one of the main sources of carbon dioxide. If we use less electricity, we will produce less C02.
In conclusion, if we make small changes now in the way we live, we can avoid huge changes in the future. Scientists, governments and individuals must work together to overcome this threat.
Answer:
HERE IS YOUR ANSWER
Explanation:
GLOBAL WARMING is definitely the single greatest environmental challenge that the planet earth is facing at present. It is essential to understand the gravity of the situation. The fuel which you use in order to power your homes, cars, businesses and more is heating up the planet faster than expected. We are recording the hottest days and decades ever. What’s alarming is that the temperature of the earth has climbed to the highest point it has ever been in the past 12,000 years. It only gets worse from here if we don’t stop it now.
IMPACT ON THE GLOBAL WARMING:
As the planet is getting hotter, we need to collectively act right now instead of waiting for more. The primary cause of global warming is fossil fuels. Human beings are addicted to burning them which produces coal, oil, greenhouse gases and more.
The power plants, cards, and industries produce Carbon dioxide which stays in the atmosphere for 5 decades or more. This is the reason why the temperature of the earth rises.
Due to this rise in temperature, the oceans are rising and the coral reefs are dying. Many aquatic species are going extinct while the glaciers are melting. You will be surprised to know that Greenland is losing 20% more mass than it receives from new snowfall.
Thus, it will keep shrinking as the earth warms. Moreover, extreme weather patterns are for everyone to see. The heatwaves, droughts, floods, are now taking place with greater intensity and frequency.
The hurricanes are doubling up in nature in terms of occurrence and the Katrina Hurricane is enough to prove this point. Further, the Greenland and Western Antarctic ice sheets are at great risk of melting completely. Please note that these two ice sheets presently hold around 20% of the Earth’s freshwater. The rise in sea levels will damage the coastal areas globally. Moreover, the regularity of hurricanes, tornadoes, and others may become more volatile spreading malaria and other deadly diseases.
WAYS TO TACKLE THE GLOBAL WARMING:
The time is now to do something to prevent global warming, otherwise, it will be irreversible. Electricity and transportation contribute largely to global warming, so we must begin there. It is important to note that there is no silver bullet and we must all come together to tackle global warming as a whole. Every home, business, industry, individual effort is required to tackle this crisis.
As coal produces tons of Carbon dioxide annually, we need to find ways to clean up coal. We can also tackle global warming by beginning with putting agriculture in the system. We must encourage farmers to adapt to greener farming practices. For instance, they must till land less often, and plant trees on vacant land.
Moreover, the same regime needs to be applied to other industrial producers of carbon dioxide. For instance, the transportation industry of cars, trucks, planes and more produce 28% of the carbon dioxide emissions. Thus, we must reduce these emissions by enhancing the fuel efficiency of the vehicles. Also, it is high time we got rid of oil and gasoline-based fuels and opt for greener alternatives.
On an individual level also, we must work to adopt a greener and healthier lifestyle. Try to drive less and walk more or take public transport. Get into the habit of recycling and avoid unnecessary wastage of goods. Save electricity by switching off appliances when not in use. Most importantly, plant a tree as a single tree can absorb one ton of carbon dioxide in its lifetime. Thus, remember, the change begins with you.
