Before going to the definition of overfishing we need to know the Definition of bycatch. Overfishing pushed many commercially important fish populations into steep declines for example Canada's northern cod.Some commercially important stocks are in such a critical state that all fishing has been shut down,or sharply curtailed. 1.

During past few decades, the large increase of demand especially for marine fish and marine fishery products leading to increase fish price faster than prices of meat. 2. 3. 4.Using smaller mesh size net : Overfishing.

Whaling Information and Whale Hunting Facts

But, despite bans on commercial whaling and the trade in whale products accepted by most countries, whaling is still carried out by Japan, Norway and Iceland, who kill 2000 whales between them each year and also continue to trade in whale products – it has to STOP. Once it became apparent that the numbers of whales being killed were putting whale populations under threat, a ban on commercial whaling (hunting for commercial profit) was introduced in 1986 by the body that regulates whaling – the International Whaling Commission. However, over 30,000 whales have been killed since the ban came into effect because of loopholes that have allowed some countries to carry on whaling. The International Whaling Commission currently allows Norway to hunt under an ‘objection’ to the ban, and Japan uses a loophole which allows countries to hunt whales for ‘research purposes’.

Be green/blue Elevated water temperatures, mainly due to global warming, are disrupting the ocean’s balance and consequently its health. Reducing our carbon footprint, eating organic foods, conserving water, and consuming non-toxic products can help lessen these destructive effects. REMEMBER: REDUCE, REUSE, RECYCLE! 2.
