It is hard to believe that habitats like this could possible have previously held rainforest which produces enough soft fruit for monkeys like this. Just 10,000 years ago crops were a new thing, in the same way that cows and other livestock farming. Before this, we had to hunt for virtually everything.
The reason that they can work out what monkeys ate, is because they have seen the teeth, and they were not chipped at all, as a result of soft diet. There are thought to have been roughly 5 species of this small monkey family living at the time (30 million years ago). This is new, as formerly it was thought that early primates ate some fruit but also harder foods – clearly they specialized in fruit earlier than we thought.
Around the world there are around 3 billion cattle and sheep. These produce around 231 billion pounds of methane each year, which is around 10 billion metric tonnes of methane into the air. Remember that over the first 20 years (it reduces after this) methane traps roughly 80 times the same amount of carbon dioxide. So this is the equivalent of a huge amount of carbon.
To put this in perspective, if we shrink the worlds carbon emissions to zero, but are left with all this methane, we are likely to have runaway global warming anyway.
So what does this seaweed do? It essentially causes the cows and sheep to create less methane. How much? Well, while around 100 million tonnes of this seaweed would be needed, they could eliminate 98% of the methane emissions from these livestock!
In 2019 around 34.7million tonnes of seaweed was farmed, which is leading some sceptical researchers to suggest that it cannot be done. However, if we look logically, this is already enough seaweed to reduce methane emissions by 1 third – not to be sneezed at.
Another problem, is that currently Greener Grazing is restricted to only growing 1/3 of the year, as the water temperature kills the seaweed the rest of the time. However, this could be fantastic – if cross breeding can give this seaweed the ability to cope with warmer water, they might be able to meet the whole worlds demands.
More work is needed, and other tests have proved less successful in the reduction of methane, but still, this is a field, where we might be able to green peoples behaviour without requiring them to stop eating meat.
Now, of course, if meat grown in a lab could reach price parity, it may deal with this problem overnight, though it would also eliminate many peoples source of income.
Time will tell if this company is going to have a large effect or not. We need to have farmers wanting this additive, thereby creating a valuable market for coastal communities around the world.
Milk is an important part of the diet of many people in the west, alongside other dairy products. It has, in recent years been one of the problems: while many people have cut down on eating beef, far fewer has cut down on dairy – but now, if you do not eat beef, you can stop supporting dairy farmers all together.
This is not to say that dairy farmers are bad. Governments need to create different careers and paths for these people to take out of their current work.
