Heya there,
Here's the answer you were looking for :)
"Together we have the power to protect the ocean".
About 40 to 50 percent of the world's population live within 200 km of a coastline. That proximity is just one example of the oceans' importance in our lives. Global trade, energy, and food security are the most visible "services" the oceans provide daily. Yet, our survival depends on the ocean's "invisible" services like oxygen production (providing 50-80% of global oxygen supply), carbon sequestration (capturing 25% of man-made CO2 emissions), and climate regulation (transferring 50% of global heat).
The United Nations and other international bodies have identified critical pressures facing the oceans, all of which are caused or exacerbated by human activities:
- Among global climate change effects are rising sea levels and warming waters. Coupled with ocean acidification, these pressures are deteriorating physical and biological conditions in the oceans.
- Marine pollution is another major source of pressure on the oceans. Land-based activities account for 80% of marine pollution whose volume continues to increase.
- Over-extraction and the unsustainable exploitation of marine resources result in an ever more damaging effect on marine environments and marine life. This impact is particularly disruptive when it occurs in combination with the destruction of habitats that are essential to many marine services.
- In addition to the loss of healthy habitats, the introduction of invasive species through human activities reduces the populations of native species and instigates destructive ecological change.
The scientists return to their home countries with new nuclear methods to help monitor these pressures. The precise knowledge derived from nuclear and isotopic techniques allows developing countries to make informed decisions to conserve the oceans and guide development to sustainably use ocean resources and services.
