How does pollution affect marine life?
It is estimated that up to 13 million metric tons of plastic ends up in the ocean each year—the equivalent of a rubbish or garbage truck load’s worth every minute. Fish, seabirds, sea turtles, and marine mammals can become entangled in or ingest plastic debris, causing suffocation, starvation, and drowning.
What is the impact of pollution in the sea?
Pollutants in the ocean make their way back to humans. Small organisms ingest toxins and are eaten by larger predators, many of which are seafood that we eventually eat. When the toxins in contaminated animals get deposited in human tissue, it can lead to long-term health conditions, cancer and birth defects.
What are some pollutants that harm the marine life?
Chemical pollution is the introduction of harmful contaminants. Common man-made pollutants that reach the ocean include pesticides, herbicides, fertilizers, detergents, oil, industrial chemicals, and sewage.
How does pollution affect fish?
Pollution can directly kill or harm fish, or change the makeup of the fish’ surroundings, killing off sources of food or causing plant or algae overgrowth that starve the fish of oxygen.
How does pollution affect the environment?
Pollution may muddy landscapes, poison soils and waterways, or kill plants and animals. Long-term exposure to air pollution, for example, can lead to chronic respiratory disease, lung cancer and other diseases. Toxic chemicals that accumulate in top predators can make some species unsafe to eat.
Why do fish not survive easily in polluted water?
Fish need a certain amount of dissolved oxygen to survive. The oxygen level can get out of balance quickly. In polluted water, there might be too high an amount of oxygen, consuming bacteria that decompose wastes. Excessive growth of algae is a frequent cause of oxygen depletion and sudden fish kills.
What are some harmful effects of water pollution?
Infectious diseases, like cholera, typhoid fever [6] and other diseases gastroenteritis, diarrhea, vomiting, skin and kidney problem are spreading through polluted water [7]. Human health is affected by the direct damage of plants and animal nutrition.

How many fish are killed each year because of pollution?
The Problem: Over 1 million marine animals (including mammals, fish, sharks, turtles, and birds) are killed each year due to plastic debris in the ocean (UNESCO Facts & Figures on Marine Pollution). Currently, it is estimated that there are 100 million tons of plastic in oceans around the world.
How many animals die a year due to pollution?

What illnesses can pollution cause?
Long-term exposure to polluted air can have permanent health effects such as: Accelerated aging of the lungs. Loss of lung capacity and decreased lung function. Development of diseases such as asthma, bronchitis, emphysema, and possibly cancer.
Does pollution reduce the life of human beings?
Globally, the AQLI reveals that particulate pollution reduces average life expectancy by 1.8 years, making it the greatest global threat to human health. By comparison, first-hand cigarette smoke leads to a reduction in global average life expectancy of about 1.6 years.
What can government do to reduce pollution?
What policies can a government use to reduce pollution? Pollution is a negative externality – a cost to society. To reduce pollution, the government can use four main policies – tax to raise the price, subsidise alternatives, regulations to ban certain pollutants and pollution permits.
How can we reduce industrial pollution?
This can be done in two ways. Firstly, you can reduce the amount of packaging on the products that you produce. Secondly, compare the packaging of any products you purchase. Many products have reduced packaging when bought in bulk, so this can be a fantastic way of reducing the amount of waste you produce.
