The increase in the temperature of the sea is forcing the fish to leave their habitats traditional to search for colder waters and increasingly species can be affected if targets are not met to control the increase in temperatures, which endangers the survival of their fish, they see how it reduces the oxygen in the water and its reproduction is difficult.
Smaller fish, and changes in DNA
According to a recent study published by Nature magazine, fish size could be reduced by up to 24% due to global warming.

Elevated temperatures associated with global warming can result in changes in a variety of phenotypic traits in fish.
Scientists point out that the lack of measures to reduce greenhouse gas emissions will have an impact on marine ecosystems greater than was thought.
Effects on fishing activity
Fish with biological alterations, smaller fish or contaminated fish and in lesser numbers significantly affect the economic activity and development of millions of families in the world.

Freshwater and saltwater fish generate a worldwide business of about $130 billion per year and employment for 200 million people, while feeding millions of people.
50 per cent of exported fish originate from developing countries, whose populations often find a fundamental subsistence medium in fishing.
Let's take care of our planet, change our lifestyle
At the current rate of global warming, by mid-century the average temperature could have risen to two degrees Celsius compared to the time before industrialization, a sufficient variation to cause the disappearance of up to a million Species.
What should we do?
The only way to reduce the temperature of the oceans is to significantly reduce our greenhouse gas emissions. However, even if we immediately reduce carbon dioxide emissions to zero, the gases we have already released into the atmosphere would take years to dissipate.
