The Green-House effect

A greenhouse is a house made of glass has glass walls and a glass roof and usually stays warm inside, even during winter. Sunlight shines in and keeps the interior warm. But the heat is trapped by the glass and can’t escape. So during the daylight hours, it gets warmer and warmer inside a greenhouse and stays warm at night too.

Earth’s atmosphere does the same thing as the greenhouse. Gases in the atmosphere such as carbon dioxide do what the roof of a greenhouse does. During the day, the Sun shines through the atmosphere. Earth’s surface warms up in the sunlight. At night, Earth’s surface cools, releasing the heat back into the air. But some of the heat is trapped by the greenhouse gases in the atmosphere

What causes the Greenhouse effect?

I) Deforestation

II) Burning of fossil fuels

III) Increase in population

Consequences

Some disastrous consequences of greenhouse effects are:

i) More droughts

ii) More floods

iii) Less ice and snow

iv) Rise above sea level

v) Climate change

Water Pollution

Water pollution is caused by the intentional or unintentional release of toxic chemicals/materials, contaminants and harmful compounds into various bodies of water such as rivers, lakes and the ocean.

Causes of water pollution

1) Water pollution may be caused by the intentional or unintentional disposal of hazardous chemicals and materials into a body of water.

2) Rainfall may cause polluted landscapes to disperse their poisonous materials into the water and poison the surrounding water.

3) Water pollution may also be caused by specific points or contributing factors such as large factories, oil refineries, construction sites, chemical waste management facilities, dump sites and other large scale operations that store/produce large amounts of chemical/hazardous waste

Effects of water pollution

1) Toxic rainfall can occur in areas where water and/or air is polluted with toxic chemicals and materials

.2) Polluted water can lead to sickness, disease, infections, deformities and even death among animals and plant life.

3) Once water becomes polluted it can affect people and animals either directly through consumption or indirectly through food sources, land degradation and the overabundance of plants and algae which can cover the surface of various bodies of water making it undrinkable and affecting the animals that live in that body of water.
