Solving the Climate crisis and biodiversity loss together

Yesterday I was writing about a series of dams that have collapsed in Brazil. We need to remember that there are two imminent threats that we are facing in the natural world.

  1. The world is warming. This is going to make life far harder for our children
  2. We are loosing much of the wilderness on the planet. Unfortunately we rely on this to survive in the long-term

We need to cut carbon emissions dramatically, we know as the human race that if we do not cut emissions dramatically and very fast, our planet will go through horrific change from the loss of the ice caps (and the resulting sea level rise) to the desertificion of large parts of the planet – some of this previously being rainforest.

If we cannot halt the loss of areas such as rainforests, the problem becomes even larger as we destroy one of our largest carbon sinks.

In the west, we have a responsibility to not only cut our own emissions to net zero in the space of a few decades, we must also help developing countries grow their own economies and increase the standard of living for their citizens without destroying what remains of the ecosystems that still exist.

Is bitcoin and other cryptocurrencies too energy intensive to be used?

Elon Musk has just announced that Tesla will no longer allow buyers to pay in bitcoin. Why is this relevant to a wildlife and environment blog?

Tesla is there to transition the world to sustainable transport, as a goal. of the roughly 4.1 trillion kwh of electricity used in the USA last year roughly 500 went on bitcoin (roughly 1 in 8) or 13%.

Silvopasture

Silvopasture is the idea of integrating food crops that grow high such as orchards and grapevines, but allowing grazers to graze underneath on grass. Is also often known as Agriforestry

In theory many farm areas would be capable of producing large quantities of grape vines (or other fruit) without reducing the amount of sheep that they feed on their land.

Open woodland such as this grows grass as fast as meadows, so produces as much grazing for cattle, yet absorbs many tonnes of carbon dioxide per year.

Agrovoltaics : what what is it and why are they interesting

There is often a concern that advances in efficiency and green technologies use more land and more resources, with these two processes that is not the case. 

Agrovoltaics involve putting solar panels above food crops. Food crops using a very small portion of the light that falls on them, and as such can often grow very effectively under solar panels so long as they don’t cut off too much of the light. Furthermore, while putting solar panels a metre or less of the ground is cheaper, these raised solar panels have a similar cost to roof based solar. 

A wide range of crops can be grown under solar panels

However there are also advantages for the the plants growing underneath. The amount of water evaporation is vastly lower, allowing more water hungry plants to grow well with less. The lower temperature also benefits many of the plant species.

Added to this of course is the ability for the farmer to sell megawatts of electricity each year. If enough farmers entered into this business and we invested in enough battery to store it for use in the evening and at night, we would eliminate the need for gas and coal powered electricity. Perhaps supporting rollout of Silvopasture could end the need for farmers to need additional finance from the government.

In the next article I will look at Silvopasture.

Lab grown meat saw funding increase 6 fold during 2020

Studies over the last few years show that 80% of of people are open to eating meat grown in bioreactors.

Lab grown meat is still meat, it just does not need to be grown in the animal

Why is this good news? Well one of the important advances with this meat is that it is thought that it could be created with a similar carbon footprint to lettuce.

Joined up effort to fight habitat loss and pandemics together

I have spoken repeatedly over the last year, about the positive impact of the epidemic. The loss of life has been horrible, and many people have suffered significant losses of different kinds. One of the advantages it is given though is a link between saving the remaining wildernesses on planet earth, and our own long-term health and wellbeing. Experts have once again stated the advantage of both fighting habitat loss and degradation at the same time as making sure that pandemics do not spread around the world again.

The idea that we might be the last generation on earth to have rainforests left to explore disgusts me. Perhaps the health of the worlds human population might give a reason to protect it

Republicans and fox news have decided that cut Biden has promised to make will mean 4 pounds of meat a year

The need for America to cut it’s carbon footprint by 50% in the next decade under biden’s plan has been attacked to absurd proportions.

Republicans have been arguing against doing something about climate change for decades. It should therefore be borne in mind that the speed of cuts necessary now has been made necessary by previous republican governments. Now this has to be remembered that this did not come from something Biden said, and in there more honest moments some republicans will admit this, unfortunately for the time being though it is clear that the noisy republicans are all in with this fake attack. 

Here is an explanation of the problem
