What is thin, green and rich in climate change?

If you have estimated algae, you are right.

New research published in communication Earth and Environment shows that the growth of algae in Canada’s lakes is increasing – even remote people – and climate change is the main criminal.

A team led by researchers at McGil University at Montreal and Universit Lawal analyzed the sediment core taken from 80 lakes across the country and found that most of them have been growing algae since the mid -1800s.

For the lead author Hamid Ghanbari, the most interesting discovery was a spike in the rate of growth in algal growth: since the 1960s, it increased seven times.

Ghanbari said, “It was very surprising for us and when we compared our data with other historical records, we came to know that rising temperature is a major factor.”

In addition to climate change, additional nitrogen and phosphorus are also transported from animal fertilizer and chemical fertilizers, storm water and waste water through runoff through runoff.

Along with algae, bacteria and phytoplinkon, aquatic foods are essential for the web. But too much algae can be a bad thing.

Recently published Colleague-review study Overall, Algal saw development and did not analyze to bloom.

While some lakes see some algae as a part of their cycle, Ghanbari said that what would happen if the increase in algae is normal which is normal.

“This is where the problem begins,” he said. “We don’t know what this threshold is at this time, but we know that the level of chlorophyll or algae in lakes can cause many problems.”

Ghanbari said that the growth of additional algae can harm aquatic life and even human health – reducing water quality, reducing oxygen in water and building bloom that can release hazardous toxins, as residents, as residents Lake with the banks of the eri Everyone also knows well.

Derryl McGuldric, the major of water quality monitoring and the monitoring for the Great Lakes for the environment and climate change Canada, while the algal does not necessarily do not necessarily have more toxic blooms, there is a risk for aquatic life.

“The study corresponds to what we see and (we) are the effects of suspected warming,” Macgoldric said.

Global and local action can help help

A project manager, Maëlle Tripon, a project manager, with the Fondation Revision of the Cubek Freshwater Advocacy Group said that his team had seen the first hand that when it is hot, they see more algae on the lakes.

He said that his way from research is that only local action cannot be trusted by dealing with algal growth.

“We already knew that we needed to change locally – such as farming practices as well as, for example, we need a less paved and waterproof surface in cities,” he said.

“But the study shows that we also need global policies to reduce climate change.”

Ghanbari agreed, but said that personal options can still help reduce algal development.

“To reduce fertilizers such as simple tasks … or to properly settle domestic chemicals, these simple tasks can actually help the lakes,” he said.
