Introduction
Hello steemians! I would like to welcome you to the second lecture on the four month course on the effect of environmental pollution. In this lecture,I will be talking about global warming and it's effect on our health and surrounding. Read on.

Main point
Global warming is one of the world's environmental issue,it's is the unusual increase in the earth surface temperature.
It occurs when carbon dioxide and other air pollutant in the air absorbs sunlight and solar radiation that evaporate through the earth surface. This pollutant last for centuries in the artmosphere it generates heat making the temperature of the earth hotter.
This pollutants such as carbon dioxide, Methane,Nitrous oxide and water vapour are examples of gases that causes Global warming. This gases are known as Greenhouse gases. Among all this gases mention carbon dioxide is the primary green house gasr responsible for Global warming. Gerrn house gases are usually emitted by human activities such as combustion of fossil fuels and diesel.

Effect of Global Warming on our Environment
As I said earlier, global warming is one of the major environmental challenges. The effect of Global warming in our environment includes the rising of the earth temperature which could trigger many types of environmental disaster such as earth quake ,volcanic eruption, storms, hearts waves,floods.

Effect of Global warming on human life's
When global warming occurs, the temperature of the earth increases making the sun more hotter and unbearable for humans. They hotness of the sun affects human health and leads to the damage of the respiratory system,diarrhea,damage of kidney among other kind of illness.

Effect of Global warming on Plants

This is a favourable conditions to plants as it allows efficient photosynthesis. Plants grow well in this condition through the presence of the carbondioxde and sunlight present when global warming occurs.

Effect on Aquatic life
When global warming occurs, the aquatic bodies absorbs excess heat which leads to the rising of the aquatic bodies temperature thereby surpassing the ranges if temperature in which aquatic animals live. It results to the death of the aquatic animals.

Ways to prevent Global warming

The green houses gases are constantly increasing, there by the global temperature is getting more hotter. The main cause of global warming as I earlier said are green house gases.
The way to prevent global warming is to reduce the amount of carbon-dioxied in the air. Here are some ways to prevent global warming.

• We should avoid deforestation
• Planting of trees should be encouraged
• Avoid the use of fossil fuels like petroleum and deseil.
• The use of naturel form of energy such as solar and wind should be encouraged
• The recycling method of waste disposal should be encouraged
• Awareness about the effect of global warming upon our environment and health should be created.

Global warming and climate change
People mostly use this two terms interchangeably. Therefore I would like to give a simple different explanation of this two terms.
Global warming as earlier said refers to the rise in global temperature due to the high level of concentration of green house gas.
Climate change refered to the increasing changes in the major of climate such as temperature and wind patterns over a relative period of time. From this explanation, global warming is seen to be one of the aspect of climate change.

Thank for reading, keep in touch for the next lecture.
