My Lords, I listened to the noble Lord, Lord Blencathra, with a degree of sympathy for what he is trying to achieve. We all want to make legislation more simple and able to be understood by members of the public, but in this instance, I agree with the noble and learned Lord, Lord Hope of Craighead, and the noble Baroness, Lady McIntosh of Pickering. To change the name in the legislation at this stage would cause a level of disruption, because we already have international agreements that refer to “biodiversity”. The Dasgupta report also referred to it.
There is a simple difference between nature and biodiversity. According to my dictionary definition, nature covers all existing systems created at the same time as the earth, whereas biodiversity is the part of nature that is alive, born on a mineral substrate in an earlier geodiversity. Biodiversity provides numerous ecosystem services that are crucial to human well-being at present and in the future. Longer-term changes in climate affect the viability and health of ecosystems, influencing shifts in the distribution of plants, pathogens, animals and even human settlements. Biodiversity loss has negative effects on several aspects of human well-being, such as food security, vulnerability to natural disasters, energy security and access to clean water and raw materials. It also affects human health, social relations and freedom of choice.
Quite simply, through this legislation, we need to protect our living biodiversity. The inclusion of a target-setting framework is a welcome part of the Bill, and something that has already been referred to by the noble and learned Lord, Lord Hope of Craighead. The long-term nature of environmental matters makes this all particularly important. Environmental improvement cannot be achieved over the short timeframe of a political cycle. We need to ensure that this Environment Bill provides an opportunity for the UK to become a world leader in the fight against all forms of pollution and biodiversity loss and in mitigating the impact of the climate emergency. The litmus test
for all of us in the Lords is does changing “biodiversity” to “nature” in this Bill strengthen and toughen its provisions, does it weaken existing legal protections or does it make any difference?
I believe this Bill must turn the tide on nature’s decline, biodiversity decline and the climate emergency. It must transform the way we manage waste, protect our precious water resources and all the other aspects. So, I think at this late stage, it is best to keep to the term “biodiversity”, while I fully understand and appreciate the case made by the noble Lord, Lord Blencathra.
