What does the ocean provide for humans?
The ocean provides us with the necessary resources to survive: oxygen, water, and food. Even if you do not eat seafood, fishmeal is used to feed poultry and pork, as well as to organically fertilize crops for millennia. Fish and other seafood are vital for good nutrition.
How do human systems affect the ocean?
Habitat Destruction. Virtually all Ocean habitats have been affected in some way via drilling or mining, dredging for aggregates for concrete and other building materials, destructive anchoring, removal of corals and land “reclamation”.
Do Coral reefs produce oxygen for humans?

Do trees improve air quality?

Can trees clean the air?
Trees absorb odors and pollutant gases (nitrogen oxides, ammonia, sulfur dioxide and ozone) and filter particulates out of the air by trapping them on their leaves and bark. In one year an acre of mature trees can provide enough oxygen for 18 people. As trees transpire, they increase atmospheric moisture.
What will happen if there are no trees on Earth?
Life could not exist on Earth without trees because they produce most of the oxygen that humans and wildlife breathe. Trees absorb carbon dioxide from the atmosphere and release oxygen using the process of photosynthesis. There would also be no rain without trees.
What does a tree absorb on killing a tree?

Why do we need fresh air?
It helps clear your lungs. Fresh air generally has higher levels of oxygen (not to mention lower levels of pollution) than indoor air. Exposure to more oxygen causes the blood vessels in your lungs to dilate, which improves cleansing and tissue repair within them, and helps them exchange gases more easily.

Is it OK to swim in rain?
Avoid contact with open waters during rainstorms to reduce your chances of encountering dangerous conditions. It’s also a good idea to stay away from your pool when it’s raining because your deck and other surface areas can be more slippery than usual.

What happens to the air when it rains?
As a raindrop falls through the atmosphere, it can attract tens to hundreds of tiny aerosol particles to its surface before hitting the ground. The process by which droplets and aerosols attract is coagulation, a natural phenomenon that can act to clear the air of pollutants like soot, sulfates, and organic particles.
Is rain water clean or dirty?
Most rain is perfectly safe to drink and may be even cleaner than the public water supply. Rainwater is only as clean as its container. Only rain that has fallen directly from the sky should be collected for drinking. Boiling and filtering rainwater will make it even safer to drink.
