Environment Bill

Debate between Viscount Trenchard and Baroness Ritchie of Downpatrick

Committee stage
Monday 21st June 2021 Lords Chamber

[Baroness Ritchie of Downpatrick (Non-Afl) [V]]

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.

[Viscount Trenchard (Con) [V]]

My Lords, I was much elated to read my noble friend Lord Blencathra’s amendments. I completely agree with him that “biodiversity” is one of the worst examples of a pseudointellectual word that most people do not understand and would never use in speech. I think my noble friend is right that, in the main, it would be much better if we used the easily comprehensible word “nature”, on which there is universal agreement on its meaning. I completely agree that it is highly desirable that the Bill should use language with which the public identifies.

It is interesting that, in their response to The Economics of Biodiversity: The Dasgupta Review the Government refer to

“nature, and the biodiversity that underpins it”.

This suggests that biodiversity and nature are not quite the same thing because one underpins the other, but even in a note to the preface to the review, Professor Dasgupta writes that

“the terms Nature, natural capital, the natural environment, the biosphere, and the natural world are used interchangeably.”

The Cambridge Dictionary website informs me that biodiversity means:

“the number and types of plants and animals that exist in a particular area or in the world generally, or the problem of protecting this”.

The first part of this definition sounds to me to be the same as nature, but then I am confused by the notion of protecting it. The “bio” of biodiversity is derived from the Greek bios, meaning life, and all the varieties of animal and plant life on the planet are indeed diverse.

So, although academics may disagree that the simple word “nature” is inadequate, I am not convinced that there is any material difference in meaning. I agree with my noble friend that we should change the word “biodiversity” to “nature” wherever possible. My noble friend’s Amendment 203 changes the “general biodiversity objective” of the Natural Environment and Rural Communities Act 2006 to the “general nature objective”. Perhaps the Minister could tell us whether that Act was the first in which the term “biodiversity” was used and whether he agrees that it would be much better if our law was written in language that people can understand.

The noble and learned Lord, Lord Hope of Craighead, suggested that “biodiversity” is the correct word because it is broader, but I am not sure that the noble and learned Lord persuaded me that “nature” is narrower than the whole diversity of life. I also worry for the future of the word “diversity” which increasingly carries connotations of gender and race. For all these reasons I support what my noble friend Lord Blencathra is trying to do.
