Global warming
Md. Minhaz Khan:
Global warming
“Homeâ€, an environmental documentary about Earth, depicts the future effect of global warming. How Bangladesh would be directly affected has been illustrated in it. While the impact of global warming has become a great concern for the people of the world, we have taken very few steps to combat it. The documentary warns that the future would be devastating if the pollutions are not minimized immediately. Dhaka, one of the most polluted cities in the world, would face massive problems.
The documentary provides very significant information like:
--5000 people a day die because of dirty drinking water.
--1 billion people have no access to safe drinking water.
--1 mammal in every 4, 1 bird in every 8, 1 amphibian in every 3, is threatened with extinction.
Let us play our part to combat global warming.

Day by day we have faced many natural disaster for global warming. Global warming is affecting many parts of the world. Global warming makes the sea rise, and when the sea rises, the water covers many low land islands. This is a big problem for many of the plants, animals, and people on islands. The water covers the plants and causes some of them to die. When they die, the animals lose a source of food, along with their habitat. Although animals have a better ability to adapt to what happens than plants do, they may die also. When the plants and animals die, people lose two sources of food, plant food and animal food. They may also lose their homes. As a result, they would also have to leave the area or die. This would be called a break in the food chain, or a chain reaction, one thing happening that leads to another and so on.
How to Prevent Global Warming:
Global warming refers to the Earth's air and oceans gradually heating up to a point that disrupts balance, a problem that is continually getting worse. It sounds like a problem too massive for any one individual to take on, but it really isn't. Combining any few of these suggestions can make more of a dramatic effect than most people understand. The goal is to emit less carbon dioxide into the atmosphere.
Instructions:
# Drive less. Take bikes, walk or carpool whenever possible.
# Consider investing in a hybrid or electric vehicle to help prevent against further global warming.
# Replace all the light bulbs in and around your home with energy-efficient fluorescents that use fewer watts for the same amount of light.
# Clean or replace your filters monthly.
# Choose energy-efficient appliances when it's time to buy new ones.
# Decrease your air travel.
# Wash clothes in cold water and line-dry whenever possible.
# Use a low-flow shower head, which will lessen the hot water used but not drop your water pressure in the shower.
# Cut down on your garbage-buy fewer packaged materials to prevent further global warming.
# Unplug electronics when they are not in use, because they still take up energy. At the very least, turn items off when they're not being used.
# Run the dishwasher and clothes washer only when you have a full load, and if available, use the energy-saving setting.
# Insulate your home better, and don't forget to repair or replace worn caulking or weather-stripping. Insulate your water heater.
# Buy recycled paper products and recycle as much of your waste as possible.
# Bring your own reusable canvas grocery bags when grocery shopping.
# Plant a tree.
# Have an energy audit done on your home so you can find the trouble areas and fix them.
# Use nontoxic cleaning products.
# Shop locally for food. A farmer's market is an excellent place to visit. And choose fresh food over frozen foods. Fresh takes less energy to produce.
# Keep your car tuned up, and check tire pressure often to save gas.
# Eat less meat and more organic foods in your diet to do your part in preventing global warming.
