Human Impact On Oceans
1. (Plastic) Pollution
Certain plastic items such as plastic bags can be mistaken as food for marine animals. Plastic rings from cans and bottles.
2. Overfishing / overhunting marine animals
This can impact biodiversity. Fishing and hunting too much within a short amount of time causes animal types to not replace quickly enough, which could cause them to go extinct.
3. Oil spills.
Animals ranging from birds to dolphins can lose their lives. Not only are animals being impacted, but also coral reefs and plankton.
Like pollution, animals can mistake trash/litter as food. Trash such as cigarettes and other harmful substances can get into the animals as well.
5. Habitat destruction
The animals that used to live here no longer have a place to live. These organisms can either move away or even die, which reduces biodiversity.
Ways to combat these issues
2. The Marine Mammal Protection Act was passed in 1972. This law makes it illegal to hunt and fish for marine animals without a permit.
3. The Dawn (dish soap) company is responsible for rescuing hundreds of animals' lives. They have also donated more than $4 million to the Marine Mammal Center.
4. Every state has passed a law making it illegal to litter. Each state has its own consequence(s) and fines. For texas, depending on the amount littered, you can be fined anywhere from $10-$1000+. It is also possible to be imprisoned.
5. The Texas Parks and Wildlife department creates artificial reefs.
