Does water pollution influence the evolution of plankton?
Yes, of course. Plankton are living organisms, and like us are sensitive to pollution.
Certain plankton are more sensitive than others, and therefore are at risk of disappearing. Others find ways to adapt and become more resistent.This is the type of plankton that evolves. In an ecosystem, one kind of plankton will almost always replace another that is disappearing. In this case the ecosystem itself changes. This transformation could have consequences on other organsims that feed on plankton. Any change in the composition of a community within an ecosystem could have very important consequences. If the concentration of a pollutant is very high, it could become toxic for all organisms and the entire ecosystem might die. In this situation, only certain bacteria would be able to survive, and after a certain time, the area would become clean.The time necessary depends on the toxicity and the concentration of the pollutant. A new ecosystem can develop, and in this way life continues.

Ban Ki-Moon, Secretary General of the United Nations speaks to Tara at Rio +20

Part of the speach :
"Earlier this year, I had the chance to board the Tara Expeditions when it docked in New York.
The crew was really inspiring. They shared so much information with me about oceans and climate change. I am really grateful that they are raising awareness around the world … and I am very proud that the United Nations is supporting them.
As I stood on the Tara that day in February, I stood on the deck and looked out at downtown Manhattan. We were surrounded by skyscrapers but we had a window on the deep blue sea. It was a reminder that our worlds are connected.
I promised the crew that I would continue working with dedication for the planet’s oceans.
Now, Rio has to put more wind in our sails, so we can navigate the waves to a better future.
Let us advance for our oceans and our world."
