Unravelling the Mystery: Investigating the Decline of Monarch Butterflies in Mexico

As a result of pesticides and Climate Change, the endangered insect species lost approximately 59% of their entire population in Mexico within the past year. This is the second-lowest recorded population of Monarch butterflies in Mexico in history. The species population is not counted individually, but rather by the hectares they cover, this year the level reached 0.9 hectares, dropping from a prior 2.21 hectares. With the lowest level being in 2013, at 0.67 hectares. for scale the largest international football field is approximately 0.82 hectares.

“It has a lot to do with climate change,” stated Gloria Tavera, the commission’s conservation director. She cited natural phenomena such as storms, drought and higher temperatures, all induced to higher extremes by climate change.

the largest contributor by far to the species’ decline is illegal logging, which caused a 58.7 hectare loss of habitat, which is roughly equivalent to 71.5 largest international football fields, or 3 of the Rungrado North Korean Stadium.

Restoration of endangered rainforest in Devon

‘Ancient rainforest to be restored in Devon, with 100,000 trees planted this winter’

In north Devon about 100,000 new trees have been planted as an ‘attempt to boost wildlife’ by providing new habitats. This also acts as a carbon store and aims to ‘offset climate change… purify air and water’ while creating a ‘species-rich’ area.

Florida turtle nests recovering.

A survey of nesting sites revealed a sharp increase in the amount of green sea turtle nests this year with volunteers counting more then 74,000 nests, a staggering 40% increase from 2017s record. The increase is most likely due to the conservation measures put in place after green sea turtles were listed under the endangered species act in 1978.


The catch is though, the sex of a baby sea turtle is not determined by its DNA but by the temperature of the sand in which its egg develops. cooler temperatures mean males and warmer means females. This is means that due to global warming most of the hatchlings are female. This will be a boom for the sea turtles as females can lay between 2 and 9 clutches of a 110 eggs each in a season but research suggests that climate change will outstrip the adaptive advantage of feminization.
